The records of all patients who were examined for silicosis at the Fund of Occupational Diseases between 1972 and 1976 are reviewed. In 3627 cases the mechanographical record was incomplete leaving 40 376 patients in the study. Electrocardiographic signs of chronic cor pulmonale (C.C.P.) were detected in 5.58 per cent. The severity of C.C.P. was evaluated and the prevalence of the different electrocardiographic signs was examined. The presence and severity of C.C.P. was compared to the radiological stage of silicosis, to the pulmonary function, to the duration of professional exposure to the risk of silicosis and to the use of tobacco. The value of the electrocardiographic signs of C.C.P. was evaluated. It is concluded that the mechanographical record obtained in insurance medicine is a valuable tool for statistical analysis of a disease and that C.C.P. is an infrequent and mostly late complication of silicosis.
回顾了1972年至1976年间职业病基金组织对所有接受矽肺检查患者的记录。在3627例病例中，机械记录不完整，因此本研究中有40376名患者。慢性肺源性心脏病（C.C.P.）的心电图征象检出率为5.58%。评估了C.C.P.的严重程度，并检查了不同心电图征象的患病率。将C.C.P.的存在和严重程度与矽肺的放射学分期、肺功能、职业接触矽肺风险的持续时间以及吸烟情况进行了比较。评估了C.C.P.心电图征象的价值。得出的结论是，保险医学中获得的机械记录是对一种疾病进行统计分析的宝贵工具，并且C.C.P.是矽肺一种罕见且大多为晚期的并发症。
